Updated information regarding the rating of this examination may be posted on the New York State
Education Department’s web site during the rating period. Visit the site http://www.emsc.nysed.gov/osa/ and
select the link “Latest Information” for any recently posted information regarding this examination. This site
should be checked before the rating process for this examination begins and at least one more time before the
final scores for the examination are recorded.
PHYSICAL SETTING/PHYSICS – continued
Directions to the Teacher
Follow the procedures below for scoring student answer papers for the Physical
Setting/Physics examination. Additional information about scoring is provided in the publication
Information for Administering and Scoring Regents Examinations in the Sciences.
Use only red ink or red pencil in rating Regents papers. Do not attempt to correct the
student’s work by making insertions or changes of any kind.
On the detachable answer sheet for Part A and Part B–1, indicate by means of a checkmark
each incorrect or omitted answer. In the box provided at the end of each part, record the number
of questions the student answered correctly for that part.
Students’ responses must be scored strictly according to the Scoring Key and Rating Guide.
For open-ended questions, credit may be allowed for responses other than those given in the
rating guide if the response is a scientifically accurate answer to the question and demonstrates
adequate knowledge as indicated by the examples in the rating guide.
Fractional credit is not allowed. Only whole-number credit may be given to a response. Units
need not be given when the wording of the questions allows such omissions.
Raters should enter the scores earned for Part A, Part B–1, Part B–2, and Part C on the
appropriate lines in the box printed on the answer booklet, and then should add these four scores
and enter the total in the box labeled “Total Written Test Score.” Then, the student’s raw score
on the written test should be converted to a scaled score by using the conversion chart that will
be posted on the Department’s web site: http://www.emsc.nysed.gov/osa/ on Wednesday,
June 16, 2004. The student’s scaled score should be entered in the labeled box on the student’s
answer booklet. The scaled score is the student’s final examination score.
All student answer papers that receive a scaled score of 60 through 64 must be scored a
second time. For the second scoring, a different committee of teachers may score the student’s
paper or the original committee may score the paper, except that no teacher may score the same
open-ended questions that he/she scored in the first rating of the paper. The school principal is
responsible for assuring that the student’s final examination score is based on a fair, accurate, and
reliable scoring of the student’s answer paper.
Because scaled scores corresponding to raw scores in the conversion chart may change from
one examination to another, it is crucial that for each administration, the conversion chart
provided for that administration be used to determine the student’s final score.

PHYSICAL SETTING/PHYSICS – continued
Please refer to the Department publication Regents Examination in Physical Setting/Physics:
Rating Guide for Parts B–2 and C. This publication can be found on the NYS Education Department
web site at http://www.emsc.nysed.gov/osa/scire/phyratg02.pdf. Teachers should become familiar
with this guide before rating students’ papers.
Scoring Criteria for Calculations
For each question requiring the student to show all calculations, including the equation and
substitution with units, apply the following scoring criteria:
• Allow 1 credit for the equation and substitution of values with units. If the equation
and/or substitution with units is not shown, do not allow this credit.
• Allow 1 credit for the correct answer (number and unit). If the number is given without
the unit, do not allow this credit.
• Penalize a student only once per equation for omitting units.
• Allow full credit even if the answer is not expressed with the correct number of significant
figures.

To determine the student’s final examination score, find the student’s total test raw score in the
column labeled “Raw Score” and then locate the scaled score that corresponds to that raw score. The
scaled score is the student’s final examination score. Enter this score in the space labeled “Final
Score” on the student’s answer sheet.
All student answer papers that receive a scaled score of 60 through 64 must be scored a
second time. For the second scoring, a different committee of teachers may score the student’s
paper or the original committee may score the paper, except that no teacher may score the same
open-ended questions that he/she scored in the first rating of the paper. The school principal is
responsible for assuring that the student’s final examination score is based on a fair, accurate and
reliable scoring of the student’s answer paper.
Because scaled scores corresponding to raw scores in the conversion chart may change from
one examination to another, it is crucial that for each administration, the conversion chart provided for
that administration be used to determine the student’s final score. The chart above is usable only for
this administration of the physical setting / physics examination.
